Psych: Check out 32 Guest Stars You May Or May Not Remember, Including Kerry Washington, Jane Lynch and More!

One thing that Psych has been great at over the years—aside from literally everything— is booking a ridiculously talented and fairly famous list of guest stars.

From movie stars to TV stars to everything in between, somebody surprising always manages to show up on the USA comedy doing something surprising, whether they're paying homage to their most famous roles or playing something completely new. While Psych has welcomed what feels like a hundred recognizable names, we've compiled a list of thirty of our favorite guest stars that you may or may not remember. Plus, some of the most beloved guest stars looked back on their time on Psych.

Any Psych fan will know Cary Elwes as the dashingly handsome and brilliantly sneaky art thief Pierre Despereaux, but you might have forgotten that not one, but two stars of the ABC hit Scandal have hung out in fake Santa Barbara with our favorite non-detectives. We didn't have four hundred hours to build this gallery, so we only included thirty, leaving the rest to live in the permanent gallery of our hearts...and also here in this honorable mention list.

And of course, we'd be this crevice in my arm if we didn't include Curt Smith, the Tears for Fears frontman and longtime best friend of Psych, who has played himself a total of three times on the show.

So, click through the gallery of some of the show's most famous guest stars, including a few who offered up some kind words about their time on the show ahead of its finale on Wednesday, March 26. Then head on down to the comments to tell us which guest stars were your favorites and how much are you going to miss this show when it's gone.
